VIC-3D™超高速系統(tǒng)概覽 UHS System Overview

VIC-3D UHS™交鑰匙系統(tǒng)是VIC-3D產(chǎn)品系列的新成員。 該系統(tǒng)采用當(dāng)前市場上速度的圖像傳感器進(jìn)行超高速DIC測量應(yīng)用，可用于包括爆炸試驗、高速下的局部加速度和陶瓷斷裂研究等領(lǐng)域。 由于系統(tǒng)的幀速率高達(dá)5MHz，觸發(fā)控制在這一速度下變得非常具有挑戰(zhàn)性，而時鐘精度對于測試的成功至關(guān)重要，通過我們的VIC-Snap UHS，您可以在這一過程中節(jié)省大量的調(diào)試時間。 該系統(tǒng)*由我們的技術(shù)人員提供支持，并由我們的工程師安裝調(diào)試。

The VIC-3D UHS™ turn-key system is a new addition to the VIC-3D product line. This system utilizes the fastest cameras on the market for ultra-high-speed DIC applications, which may include explosive testing, high-velocity partial acceleration, and ceramic fracture research, to name a few. This system is capable of frame rates up to 5MHz, and with VIC-Snap UHS, you will save an abundance of time during setup. Triggering becomes extremely challenging at these speeds, so precision is paramount to a successful test. The system is completely supported by our technical staff, and is installed by our top engineers.

該系統(tǒng)具有*集成的超高速圖像采集控制：當(dāng)通過傳統(tǒng)的方式為3D-DIC的超高速（UHS）相機(jī)采集圖像時，某些制造商的采集軟件無法讓用戶獲取同步的單個圖像組(雙相機(jī)的單幀同步照片*)，而這是3D標(biāo)定的必要條件。 隨著VIC-Snap UHS的發(fā)展，用戶可以通過CSI 提供的VIC-Snap UHS程序獲得單個圖像組序列實現(xiàn)標(biāo)定，并采集一系列同步的圖像組序列用于測試分析。 能夠同時為多臺相機(jī)執(zhí)行標(biāo)定與實驗過程采集的兩種圖像數(shù)據(jù)采集，可以為用戶在DIC測試的標(biāo)定階段節(jié)省數(shù)小時的時間，并簡化該流程。

Fully Integrated Ultra-High-Speed Camera Control: When acquiring images by conventional means with Ultra-High-Speed (UHS) cameras for 3D DIC, some manufacturer’s acquisition software does not have the ability for the user to acquire single pairs of images that are synchronized, which is a requirement for a 3D calibration. With the development of VIC-Snap UHS, the user has the ability to take single image sequences for calibration and a series of images for testing. Having the capacity to perform both types of acquisition for multiple cameras at once literally saves hours of time during the calibration phase of DIC testing, and streamlines the process.

* 雙相機(jī)的單幀同步照片：某些高速相機(jī)制造商的自有圖像采集控制軟件，在單次觸發(fā)下不能實現(xiàn)單張圖像采集，而是得到一組照片序列，造成在標(biāo)定時會得到幾百至數(shù)千張的圖片，這需要大量的人工時間去處理完成剔除、時間比對、命名等工作，浪費寶貴的試驗時間。通過VIC-Snap UHS可以直接得到與靜態(tài)3D系統(tǒng)相一致的手動觸發(fā)控制模式和標(biāo)定用照片組，使超高速試驗的圖像采集工作與靜態(tài)系統(tǒng)一樣的簡潔、高效且具有*的時鐘精度。
